Mechanical Bottom-up Nano-Assembling and Nano-Manipulation Using Shape Memory Alloy Nano-Gripper

Abstract

The numerous 1-D and 2-D nanomaterials: nanotubes, nanowires (NWs), graphene, etc. were discovered, synthesized and intensively studied in the past decades. These nanomaterials had appeared to reveal the unique physical and functional properties allowing constructing the large number of nanodevice based on single nanoobjects. Recently many studies have led to a wide range of proof-of-concept of individual nanoscale devices including nanolasers, nanosensors, field-effect transistors (nanoFETs) and many others based on NWs, carbon nanotubes (CNT) and many other nanoobjects. Such nanodevices represent attractive building blocks for hierarchical assembly of microscale and macroscopic devices which are attractive for creating of micro-and –macro-devices and arrays by the bottom-up and hybrid paradigm. In this paper the conceptual survey is given of nowadays achievements in the field of mechanical bottom-up nanoassembling. We emphasize on the system based on smallest and the fastest in the World nanotweezer developed on the base of the new smart materials with shape memory effect for nanomanipulation of real nanoobjects. We discuss the recent experiments on nanomanipulation, nanoassembling and nanomanufacturing of nanoand micro-devices using this method, which in many cases can replaced very expensive “top-down” technologies.
